Balance deer herd impacts on human needs, such as private property rights, agricultural crops and local economies. Maintain the population at a level that is within the long-term capability of the available habitat to support. POPULATION MANAGEMENT OBJECTIVES Target Winter Herd Size - Manage for a 5-year target population of 16,000 wintering deer (modeled number) during the five-year planning period unless range conditions become unsuitable, as evaluated by DWR. Range Trend data coupled with annual browse monitoring will be used to assess habitat condition. If habitat damage by deer is occurring due to inadequate habitat, measures will be taken to reduce the population to sustainable levels. Change to the population objective is based on this population’s performance, improved range conditions, the amount of available habitat and the lack of range damage from deer. The population objective is being restored from its pre 2002 DCI reduction. Unit 30 Population Objective History 1994-2001 Objective: 16,000 2002-2014 Objective: 12,800 2015-2020 Objective: 16,000 Change from last plan +3,200 Herd Composition – This is a General Season unit and will be managed to maintain a three year average postseason buck to doe ratio of 18-20 according to the statewide plan. Caution will be use when adjusting permits and trends will be considered. General Buck Deer hunt regulations, using archery, Rifle, and Muzzleloader hunts. Antlerless removal will be implemented to achieve the target population size using a variety of harvest methods and seasons. It is recognized that buck harvest may fluctuate due to climatic and productivity variables. Buck harvest strategies will be developed through the RAC and Wildlife Board process to achieve management objectives. POPULATION MANAGEMENT STRATEGIES Monitoring . Population Size - Utilizing harvest data, postseason and mortality estimates, a computer model has been developed to estimate winter population size. The 2014 model estimates the population at 13,500 deer. Buck Age Structure - Monitor age class structure of the buck population through the use of checking stations, postseason classification, statewide harvest survey data and bag checks. Harvest - The primary means of monitoring harvest will be through the statewide harvest survey and the use of checking stations.

Crop Depredation - Strategies will be implemented to mitigate crop depredation as prescribed by state law and DWR policy. Habitat - Public land winter range availability, landowner acceptance and winter range forage conditions will determine herd size. Excessive habitat utilization will be addressed with hunting. Predation - Follow DWR predator management policy: - If the population estimate is less than 90% of objective and fawn to doe ratio drops below 70 for 2 of the last 3 years or if the fawn survival rate drops below 50% for one year, then a Predator Management Plan targeting coyotes may be implemented on that subunit. - If the population estimate is less than 90% of objective and the doe survival rate drops below 85% for 2 of the last 3 years or below 80% for one year, then a Predator Management Plan targeting cougar could be implemented on that subunit. - The southern and eastern portion of this unit is currently under a Harvest Objective cougar management plan with the recent bighorn sheep transplants and the planned additional bighorn sheep transplants. Deer in the Browse and Beaver Dam mountain area will also benefit from this cougar management strategy. Highway Mortality - DWR will Cooperate with the Utah Dept. Of Transportation to construct highway fences, passage structures and warning signs etc if needed. Mortality along I-15, SR-56, SR-18 has been significant. At several locations on SR-56, SR-18, New Harmony and Newcastle bench roads flashing deer crossing signs have been installed in cooperation with the Utah Dept. Of Transportation, Iron and Washington County road departments. Deer fencing has been installed along I-15 between Cedar City and New Harmony. Highway mortality will be monitored and additional highway fences, passage structures and warning signs will be added if needed. Illegal Harvest - If illegal harvest is identified as a limiting factor, a unit specific action plan will be develop in cooperation with the Law Enforcement Section. HABITAT MANAGEMENT OBJECTIVES . Maintain or enhance forage production through direct range improvements on winter and summer deer range throughout the unit to achieve population management objectives. Maintain critical fawning habitat in good condition. Fawn recruitment is a major concern on this unit and may be the single greatest factor limiting the population. Work with federal and state partners in fire rehabilitation and prevention on crucial deer habitat through the WRI process . Manage public lands adjacent to areas with heavy agricultural depredation to promote deer use during late summer. Maintain and protect critical winter range from future losses. Acquire critical winter range when the opportunity arises. HABITAT MANAGEMENT STRATEGIES Monitoring . Determine trends in habitat condition through permanent range trend studies, spring range assessments, pellet transects, and field inspections. Land management agencies will similarly conduct range monitoring to determine vegetative trends, utilization and possible forage conflicts. Range trend studies will be conducted by DWR to evaluate deer habitat health, trend, and carrying capacity using the deer winter range desirable component index (DCI) and other vegetation data. The DCI was created as an indicator of the general health of deer winter ranges. The index incorporates shrub cover, density and age composition as well as other key vegetation variables. Changes in DCI suggest changes in winter range capacity. However, the relationship between DCI and the changes in deer carrying capacity is difficult to quantify. Continue existing monitoring studies, and coordinate with BLM on additional riparian monitoring. Seek opportunities to partner with Universities to coordinate research in areas of need. Habitat Protection, Improvement and Maintenance . Work with public land management agencies to develop specific vegetative objectives to maintain the quality of important deer use areas. Continue to coordinate with land management agencies in planning and evaluating resource uses and developments that could impact habitat quality including but not limited to oil and gas development, wind energy, solar energy, and transmission line construction. Coordinate with federal and state partners in designing projects that will improve fire resiliency and protect areas of crucial habitat. Work toward long-term habitat protection and preservation through the use of agreements with land management agencies and local governments, and through the use of conservation easements, etc. on private lands. Continue working toward blocking up UDWR properties through land exchange. Manage vehicle access on Division of Wildlife Resources land to limit human disturbance during times of high stress, such as winter and fawning. Manage riparian areas in critical fawning habitat to furnish water, cover and succulent forage from mid- to late summer. Protect riparian areas to furnish cover, water and succulent forage adjacent to areas with historic agricultural damage. Provide guzzlers or other water sources where needed on critical summer fawning areas or in times of severe drought. Cooperate with federal land management agencies and private landowners in carrying out habitat improvement projects. Protect deer winter ranges from wildfire by reseeding burned areas, creating fuel breaks and vegetated green strips and reseed areas dominated by Cheat grass with desirable perennial vegetation. Reduce expansion of Pinion-Juniper woodlands into sagebrush habitats and improve habitats dominated by Pinion-Juniper woodlands by completing habitat restoration projects like lop & scatter, bullhog, and chaining. Seek opportunities to increase browse in burned areas of critical winter range. Cooperate with federal land management agencies and local governments in developing and administering access management plans for the purposes of habitat protection and escape or security areas. Seek out opportunities to improve fawning habitat across the unit. Consider summer range habitat improvement projects that remove encroaching trees, improves succulent vegetation and wet meadow habitat, increases aspen recruitment, enhances and/or protects riparian areas, use prescribed fire to promote early succession habitats where appropriate.
